Pulsar Generator

Pulsar Generator (or simply PG) designed by Alberto de Campo and Curtis Roads, implements the Pulsar synthesis technique discussed in Chapter 5 it runs on Macintosh computers. 

The Control Panel lets the user start and stop a pulsar train. The duration of a pulsar train is set in the box on the right side labelled Train Duration and it can be set to repeat itself if the Loop option is checked. By clicking on the Record button one can save a pulsar train in a soundfile but what is interesting here is that the user can change the sound in real-time, while the it is being saved. The recorded file goes into the PG folder under the name PulsarGenRec. 

A quick-start overview of the system is given in the document PG ManualWord98 that is available within the PG materials. Fairly informative documentation is also provided via the program s own Help facility, including a complementary introduction to the Pulsar synthesis technique. 

Vibra 1000 is monophonic stereo synthesizer for Macintosh made by Koblo, in Denmark. In fact Vibra 1000 is the baby of an impressive family of synthesisers, the Koblo Studio 9000. This family comprises five synthesisers in one versatile bundle. These synthesisers can perform in real time and seamlessly integrate into any digital audio workstation.
